The Tampa Bay Lightning bought another big goaltender based on a small sample size.

Tampa Bay on Wednesday acquired Ben Bishop from the Ottawa Senators for, according to multiple reports, rookie winger Chris Conacher and a fourth-round pick, about an hour before the NHL trade deadline.

Bishop has been good filling in for Craig Anderson this season, but his .922 save percentage is 20 points higher than his .902 career mark in 23 games before 2013. Moving forward, Bishop (6-7) will compete for time with Anders Lindback (6-6), who struggled before injuring himself in his first season with the Lightning. He was 10-7-1 with a .903 save percentage and 2.88 GAA in 21 appearances.

Goaltending has been a problem for the Lightning, who have top prospect Andrei Vasilevski in the system. They're out of the playoff picture despite averaging 3.17 goals per game, third best in the league.

Senators GM Bryan Murray said that Tampa GM Steve Yzerman, when Ottawa acquired Bishop from the Blues for a second-round pick, said he missed the boat: "He felt that he could've addressed a need at that time."

The issue for Yzerman though, is that Conacher, despite being just 5-8, has shown potential—he has nine goals and 15 assists this season, though just two and four of those came in March. As noted on TSN, Tampa Bay also has another undersized forward, in Tyler Johnson, and a new coach, Jon Cooper, who coached both in the AHL. It's possible that they chose between the two and opted for Johnson.

Conacher will provide needed offense for the Senators, who have managed to stay in playoff position despite averaging 2.42 goals per game, 24th in the NHL, and dealing with injuries to Anderson, Erik Karlsson and Jason Spezza.

"We wish he was 6-foot-7, but he's not. He's a guy that addresses a need for points," Murray told reporters on Wednesdsy—and he didn't stop there, saying that he was aware of Conacher's exploits in the AHL.

"All I know about him is last year, all I heard was our team in Binghamton complain about this guy Cory Conacher scoring goals and (being) competitive and dirty and mean around the net, and then I saw him play this year," Murray said.
